This invention relatesto certain improve-- ments in the form and arrangement -of printing plates on a printing .plate support, and the` invention has for its special object the form and' arrangement-:of a printing plate so that the usual margin space between two plates' may be utilized for printing without a break in the printing surface of this margin space.

lIt is frequently desirable in 4printing certain products that the margin spacel usual-ly formed between two adjacent vprinting plates be utilized for printing, as, forinstance, in printing double wide pages without a` center margin or in utilising the space for late news, advertisements, or mattei'l dif-` ferent from that contained in the main body of the page.v It has been proposed lto accomplish this by casting two plates, `each with `a projecting portionfsubstantially/one half the width of the margin space, thetwo plates abutting about` the center ofthe clamp or clip used .for holding the plates on the plate support. With this construction both plates `had to be cast with these extending portions. vFurthermore, with this construction aline was produced centrally of the margin space due to the gap'between the adjacent edges of the plates. When this 0 space was utilizedfoi printing-'advertisements or late news, this line would run through such printed mattei', and for this reason this' construction was undesirable.

A construction is provided by the present invention whereby the whole of the margin space may be utilized for printing without this central line so that the space may be used for late news, advertisements, etc., with a smooth, unbroken surface, and a construction requiring but one specially cast plate. A preferred construction -fo'r effecting this is illustrated in the accompanying drawings, in connection with which the invention will now be described in detail, and

the novel featurespointed' out in the claims hereunto annexed.

Referring now -tothedrawinga the in` vention hasfbeen illustrated as employedin.l a construction in which the plate support is a cylinder, but itjwill .be lunderstood that the` linvention is'app'licabl'e to. forms lother than those v supported on. 'cylindrical or' i In the construction illustrated,ireferring l rst toiFigs. -1 and'2, the platensuppo'rt is shown as a portion of al cylinder marked 1. ln the construction shown there are two plates 2,3, supportedronthis cylinder,v these plates being formed as ordinarily, withbev-i elled edges 4 whichita'ke vunder the bevelled sides 5 of a margin ring 6.1 This margin 'ring 6 forms a part of the means for clamp,4 ing the plates on the cylinder, and the width of this ring provides the margin. Inthe construction shown this lmargin ring is separate from thel cylinder and is movable longitudinally of the cylinderv as vis usual' where a cylinder 4 plates .wide is employed.

It is to be understood, however, that this margin ring maybe made integral with the cylinder, where a cylinder i carrying two plates wide is used. This margin ring is secured by screws 7 to a clip block 8 'and a 4 shaft 9, this shaft being operated in any suitable manner, not shown, to move longitudinally of the cylinder and lock the plates in position against the ring. A stop nut 10 is or may be provided for limiting the endwise movement of the shaft and the block. This margin ring, however it lmay be secured in position on the cylinder, is lower than the slide of the plate, so as to provide v a margin space against which there will be no impression. A web printed with the con-k struction illustrated in Fig. will produce a product such as shownin Fig. 4, in which a margin space is indicated by the letter N.

In carrying out the invention, to utilize this margin space for printing as above set forth so as to produce kthe products shown in Figs. 5 and 6, one of the plates, as the pla-te 2, will be vcast or otherwise formed with an extension 11, this extension being wide enough .to extend entirely, or substantially entirely'across the margin space and over the margin ring and to abut against the bevelled edge 4 of theplate- 3, the lower inner edge of the extension being bevelled as indicated at 12 so as to makel a snug contact with the edge of the plate 3, the extension of the plate 'resting on and being supported by the ring. This'plate 2 is formed beneath the extension 11, with `an under-cut portion 14 so kthat it will take under the edges 5 of the margin ring andl he lclamped firmly in place by operating the clamp shaft 9 as before referred to. With this construction a product such as shown in Fig. 5

may be produced with the columns extending unbrokenly across a two page wide sheet, the extension of the plate 2 being prepared with the proper printing matter. Further, if

f desired,the product illustrated in Fig. 6 may various means may beemployed for vclamping the plates in posit-ion on the cylinders and various arrangements of the :plates on the cylinder may be made, vand the invention is not intended to be limited to the exact construction and arrangement shown and described.

lllhat isclaimed is:

1. The combination with a printing plate other side of the stop and providing an iiiibroken printing surface across the stop. i

3. Thecombination with a. printing'plate support, of a plate stop on the support, a plate having an ,extension projecting entirely across the stop, the outer edge of said extension being bevelled and against :the'bevelled edge of a--p'late on the other side of the stop, andtheinner edge being formed with a. shoulder taking against a cooperating shoulder on the stop,'ftlie eX- tension of Ithe plate forming .an unbroken printing surface where it projects across the stop. f

y4. The combination with a plate support, of main printing surfaces on the support, a plate stop on the support between the. main printing surfaces and spacing them to form a margin, and a printing surface narrower than the main surfaces and extendinge'rrl tirely across the margin space and providing an unbroken print-ing surfacein vsuch space.

jA printing plate formedy with a main printing surface and a shoulder adapted to engage a margin stop, and an extension projecting beyond the shoulder at one side of abutting i the plate dimensioned to extend across the i stop, said extension having an unbroken printing surface for Vprinting in the margin i space formed bythe stop. I a In testimony whereof, l have hereunto set my hand. f Y
